Preparation and visible-light photocatalytic activity of bismuth tungstate/lotus fiber composite membrane
Bismuth tungstate/lotus fiber composite membrane (Bi 2 WO 6/LF) were prepared. The
composite membranes were characterized by scanning electron microscopy (SEM), energy
dispersive spectrum (EDS) and X-ray diffraction (XRD). The photocatalytic activity of Bi 2 WO
6/LF under visible light irradiation was investigated. The result shows that photocatalytic
activity of the Bi 2 WO 6/LF increase with the rise of Bi 2 WO 6 content in the composite
membrane. Bi 2 WO 6/LF with 1% Bi 2 WO 6 possesses excellent photocatalytic activity for …

Abstract
Bismuth tungstate/lotus fiber composite membrane (Bi2WO6/LF) were prepared. The composite membranes were characterized by scanning electron microscopy (SEM), energy dispersive spectrum (EDS) and X-ray diffraction (XRD). The photocatalytic activity of Bi2WO6/LF under visible light irradiation was investigated. The result shows that photocatalytic activity of the Bi2WO6/LF increase with the rise of Bi2WO6 content in the composite membrane. Bi2WO6/LF with 1% Bi2WO6 possesses excellent photocatalytic activity for methylene blue and degradation efficiency of methylene blue reach 94% after irradiation for 270 min. Bi2WO6/LF could be potentially applied in sewage disposal and environmental remediation.
